如果您使用杰克逊解析HashMap<String,String>则将'data'定义为HashMap<String,String>

Answer 2

You can do this using Gson to parse Json to Java objects. Here is an example.

First you need to create a class for wrapping Request and Response objects.

public class RootWrapper {

    private Request request;
    private Response response;

    // Getters && Setters
}

Request is the easy one.

import com.google.gson.annotations.SerializedName;

public class Request {

    @SerializedName("Target")
    private String target;

    @SerializedName("Format")
    private String format;

    @SerializedName("Service")
    private String service;

    @SerializedName("Version")
    private String version;

    // Getters && Setters
}

And here is Response . You must use a Map to hold "44" and "22".

import java.util.Map;

public class Response {
    private int status;
    private int httpStatus;
    private Map<String, OfferWrapper> data;

    // Getters && Setters
}

Since Offer object wrapped in an other object you must use a wrapper object.

import com.google.gson.annotations.SerializedName;

public class OfferWrapper {

    @SerializedName("Offer")
    private Offer offer;

    // Getters && Setters
}

And your Offer object should look like this

public class Offer {

    private String id;
    private String name;
    private String description;
    private String url;
    private String url2;

    // Getters && Setters
}

And at last, you can convert given Json to java object.

final Gson gson = new GsonBuilder().create();
final RootWrapper rootWrapper = gson.fromJson(TEST_JSON, RootWrapper.class);

By the way, your json is not valid. There are unnecessary commas at the end of url2 tags.
